Ls1 Engine Build Rockers

With the rocker shaft bolted to the stand, adjust the checker so it butts squarely against the inside of the rocker's lash adjuster cup seat. Note: during this process, the lifters should not have any oil in them as this will throw off the reading. But if you've already soaked them (as we did last time), the lifters are easily bled down. Simply hold the checker down against the lifter plunger; the lifter will bleed down over the span of just a few seconds. Sometimes this won't work as you can't generate enough force: in this case, pull up on the tip of the rocker and you'll see it slowly lift off the valve further and further. Alternatively, turn down the adjuster and the oil will get squeezed out; it won't tighten firmly until the lifter plunger actually bottoms (just make sure you bring the adjuster back to one full turn after this).
